4.2. White Balance Adjustment
4.2.1. Overview
▪ W/B adj. Objective & How-it-works
(1) Objective: To reduce each Panel's W/B deviation
(2) How-it-works : When R/G/B gain in the OSD is at 192, it
means the panel is at its Full Dynamic Range. In order to
prevent saturation of Full Dynamic range and data, one
of R/G/B is fixed at 192, and the other two is lowered to
find the desired value.
(3) Adjustment condition : normal temperature
1) Surrounding Temperature : 25 °C ± 5 °C
2) Warm-up time: About 5 Min
3) Surrounding Humidity : 20 % ~ 80 %
4.2.2. Equipment
(1) Color Analyzer: CA-210 (LED Module : CH 14)
(2) Adjustment Computer(During auto adj., RS-232C protocol
is needed)

▪ RS-232C Command used during auto-adjustment.
Ex) wb 00 00 -> Begin white balance auto-adj.
wb 00 10 -> Gain adj.
ja 00 ff -> Adj. data
jb 00 c0
...
...
wb 00 1f → Gain adj. completed
*(wb 00 20(Start), wb 00 2f(end)) → Off-set adj.
wb 00 ff → End white balance auto-adj.
▪ Adj. Map
4.2.5. Adj. method
(1) Auto adj. method
1) Set TV in adj. mode using POWER ON key.
2) Zero calibrate probe then place it on the center of the
Display.
3) Connect Cable.(RS-232C to USB)
4) Select mode in adj. Program and begin adj.
5) When adj. is complete (OK Sign), check adj. status pre
mode. (Warm, Medium, Cool)
6) Remove probe and RS-232C cable to complete adj.
▪ W/B Adj. must begin as start command “wb 00 00” , and
finish as end command “wb 00 ff”, and Adj. offset if need.
(2) Manual adjustment. method
1) Set TV in Adj. mode using POWER ON.
2) Zero Calibrate the probe of Color Analyzer, then place it
on the center of LCD module within 10 cm of the surface.
3) Press ADJ key → EZ adjust using adj. R/C → 7. White-
Balance then press the cursor to the right(key ►).
(When right key(►) is pressed 216 Gray internal pattern
will be displayed)
4) Adjust modes (Cool) Fix the G gain to 172 (default data)
and change the others (R/B Gain).
5) Adjust two modes(Medium / Warm) Fix the one of R/G/B
gain to 192(default data) and decrease the others.

* CASE Cool
First adjust the coordinate far away from the target
value(x, y).B
1. x, y > target
2. x, y < target
3. x > target, y < target
4. x < target, y > target
Every 4 case have to fit y value by adjusting B Gain and
then fit x value by adjusting R-Gain.
In this case, increasing/decreasing of B Gain and R Gain
can be adjusted.
How to adjust
1. Fix G gain to 172 and then adjust R Gain and B
Gain(In Case of Mostly Blue Gain Saturation )
2. When B Gain > 255, Release Fixed G Gain and
Readjust
* CASE Medium / Warm
First adjust the coordinate far away from the target
value(x, y).
1. x, y > target
i) Decrease the R, G.
2. x, y < target
i) First decrease the B gain,
ii) Decrease the one of the others.
3. x > target, y < target
i) First decrease B, so make y a little more than the
target.
ii) Adjust x value by decreasing the R
4. x < target, y > target
i) First decrease B, so make x a little more than the
target.
ii) Adjust x value by decreasing the G
6) Adj. is completed, Exit adjust mode using “EXIT” key on
Remote controller.
▪ If internal pattern is not available, use RF input. In EZ Adj.
menu 7.White Balance, you can select one of 2 Test-
pattern: ON, OFF. Default is inner(ON). By selecting OFF,
you can adjust using RF signal in 216 Gray pattern.
▪ Adjustment condition and cautionary items
1) Lighting condition in surrounding area
Surrounding lighting should be lower 10 lux. Try to
isolate adj. area into dark surrounding.
2) Probe location
: Color Analyzer(CA-210) probe should be within 10 cm
and perpendicular of the module surface (80° ~ 100°)
3) Aging time
- After Aging Start, Keep the Power ON status during 5
Minutes.
- In case of LCD, Back-light on should be checked
using no signal or Full-white pattern.
4.2.6. Reference (White balance Adj. coordinate and
color temperature)
▪ Luminance : 216 Gray
▪ Standard color coordinate and temperature using CS-1000
(over 26 inch)
▪ Standard color coordinate and temperature using CA-210(CH 14)
▪ Standard color coordinate and temperature using CA-210(CH-14)
- by aging time
4.2.7. ALELF & EDGE LED White balance table
- EDGE LED module change color coordinate because of
aging time.
- Apply under the color coordinate table, for compensated
aging time.
